Threat Intelligence: Critical Maximum-Rating Vulnerability in the libwebp Library

Posted on by D1 Defend
Posted: September 9, 2023

This alert is about a very serious vulnerability—identified as CVE-2023-5129—that could be hiding all over your clients’ environments. In fact, CVE-2023-5129 is so serious that Google has stamped it with their highest severity rating: a solid 10/10.

CVE-2023-5129 was initially classified as a Chrome issue. But we now realize that it pertains much more broadly to any software that utilizes the libwebp open-source library.

Here’s the technical gist: This flaw revolves around a heap buffer overflow in WebP, related to the Huffman coding algorithm used by libwebp for lossless compression. So malicious actors can potentially take advantage of this vulnerability to execute unauthorized commands or access sensitive data by using maliciously crafted pages.

The real problem, however, is that a lot of software uses the libwebp library. So we’re looking at a vast landscape of potential vulnerabilities that includes 1Password, Signal, Safari, Mozilla Firefox, Microsoft Edge, Opera, native Android web browsers, and more.

Remediating this vulnerability therefore requires you to pinpoint every piece of software in your clients’ environments (and your own) that integrates the libwebp library.

This will be a huge undertaking. And it underscores the critical importance of maintaining a complete, accurate, and up-to-date software inventory. So we need to act fast and remediate thoroughly.

We can discuss CVE-2023-5129 further during office hours, coaching calls, and on the forum. But we need to get on this right away.

Stay tuned for new developments as this situation continues to quickly unfold.

Threat Intelligence: MGM Nightmare

Posted on by D1 Defend
Posted: September 14, 2023

Goliath has fallen.

MGM Properties got hit and they got hit hard. Yes, I’m talking about the company that owns 31 unique gambling and hotel properties. Their casino and hospitality operations were brought to their knees causing them to shutter MGM Grand and other Las Vegas properties. Gambling was shut down and patrons were left unable to enter their hotel rooms.

Who’s responsible? A group identified as “Scattered Spider” or UNC3944, an affiliate of a ransomware-as-a-service “BlackCat.”

Once they compromise a company and steal its data, Scattered Spider attacks virtual machines through virtual serial and administrative consoles and purposely inject vulnerable signed drivers to escalate privileges or move laterally within a network. They use BlackCat ransomware to strike a final blow.

The BlackCat ransomware, developed by UNC3507, or ALPHV, has been widely used by threat actors in many cybersecurity incidents in the last year. Did you know that nearly 12% of all cybersecurity attacks in 2022 involved the BlackCat ransomware, including the attacks on semiconductor manufacturer, Seiko, and the international auditing and accounting company, Mazars Group?

Scattered Spider is known for its reliance on social engineering to establish a point of entry into an organization, which means they psychologically manipulate their victims to get what they want. Then they use advanced techniques to capture critical business and personal information. As if they weren’t deadly enough, being based in the United States, Scattered Spider has an advantage over foreign adversaries. This helps them in doing scams that involve things like calling a victim and convincing them to click links, accept MFA requests, or run executables, for example.

Once into a system, Scattered Spider steals data from the organization, including business documents, personal information such as social security numbers, and client and customer data for use in double extortion. Ransomware is deployed—in this case BlackCat, developed by ALPHV—which allows Scattered Spider to extort the business for ransom. Not willing to pay a ransom? Scattered Spider then goes to work through their affiliate network to post the stolen information for the second extortion attempt.

While the MGM situation is still transpiring and many elements are still unknown, this attack highlights several areas of focus for all businesses and employees:

  • Defense In Depth is essential to ensure that a small breach doesn’t turn into a major business catastrophe
  • All employees must be continuously educated on how to resist social engineering exploits executed on them via email, text, or phone
  • Organizations must proactively run tests to ensure that their employees are in fact resisting social engineering tactics—and re-train any under-performing employees
  • Wise executives will press their suppliers, contractors, and other business partners to also take appropriate steps to assess and enhance their own security posture in order to further reduce their exposure to risk

But this doesn’t just stop with businesses and employees. Anyone who visited MGM properties is at additional risk, including those who have stayed at one of the hospitality properties or signed up for lines of credit. What should you do if this is you? Well, at the moment it’s still unclear what data was stolen, but it’s always a good idea to monitor bank accounts, credit/debit cards, and social security information.

Running a business involves taking care of a lot of moving parts. One area you might think about only sometimes is your computer hardware, which includes your servers and other parts and accessories of your computers. It is essential to take good care of your computer hardware. Regular maintenance can help your business run smoother, catch issues early, and improve system performance.

Understanding Hardware Maintenance

Hardware maintenance is like a health checkup for your computer. It means looking at, fixing, and updating the parts of your computer. These parts include the keyboard, drives, hard disk, and battery. Regular maintenance can make your computers work better and last longer. A computer that gets regular checkups can last five to eight years or even more.

Using Dashboards to Monitor Your Business Performance

Posted on by D1 Defend

Keeping track of your business success is a lot easier with dashboards. This business intelligence reporting tool helps you see your critical business metrics and key performance indicators (KPIs). With dashboards, you can make smarter decisions for your business. Let’s discuss how dashboards can bring a huge boost to your business.

What’s a Dashboard?

A dashboard is a tool that helps you aggregate and display crucial business data. It’s like a one-stop shop for all your important business info. You can track your progress over time and see which parts of your operations are doing well or need improvement.

Dashboards can reflect how a business is doing by showing important details about key performance indicators (KPIs) right when they happen. They can be set up to show the info that matters most, like finances, customer satisfaction, and how much stock you have. This lets you see what you need to know right away instead of having to look through lots of reports or tables.

Looking at KPIs with dashboards helps companies see if a problem might arise. They can then do something about it before it becomes a big issue. In short, a dashboard is a helpful tool for any business owner who wants to keep a close eye on the state of operations.

Why Dashboards Matter to Your Business

Dashboards make your business run smoother. Here’s how:

Windows Update Ransomware

Posted on by D1 Defend

When you see a Windows update, you anticipate a security improvement, not a threat. However, a sneaky extortion scam disguised as a Windows update page has recently appeared.

Its danger lies in encrypting files on your computer. The scammers then demand payment to return your files. This extortion scam is known as Big Head ransomware. Currently, it is aimed at U.S. consumers.

Understanding Big Head Ransomware

Fortinet, a cybersecurity company, discovered Big Head ransomware. Fortinet believes Big Head launched in May 2023. There are several variants designed to lock your files and demand money.

The first version shows a fake Windows Update screen. After about 30 seconds, it disappears. By then, it locked your files and changed the file names.

In some cases, you might see “README” files. These carry email addresses, Telegram account details, and even Bitcoin addresses. All these are there to collect money from you in exchange for unlocking your files.

The second version has a different method. Instead of a Windows Update screen, it changes your desktop wallpaper to a ransom note. This note asks for one Bitcoin, which is around $30,000.

Protecting Your Company

Big Head ransomware can damage your business. But you can protect yourself and your sensitive data. Here’s how:

  • Watch out for phishing scams: Most ransomware comes through these scams. Make sure you understand and can identify the telltale signs of a scam.
  • Back up your data often: The more frequently you back up, the less data you lose if attacked.
  • Choose where you back up your data carefully: Some ransomware can delete backups.
  • Secure your backup: Even if the ransomware can’t delete your backup, it might still be able to lock it. If possible, store an offline copy.

Safeguard Against Ransomware

Big Head ransomware is a severe threat. It may not be widespread yet, but it’s better to be safe than sorry. Be cautious with Windows updates, and safeguard your organization from phishing scams. Back up your data frequently and store the backups in a secure location. These measures can prevent ransomware attacks. When you safeguard your files, you protect your company.
